This invention relates to separable fasteners employing stringers with coupling links spaced longitudinally of the stringers and a slider movable longitudinally of the stringers to couple and uncouple said links; and the object of the invention is to provide an end coupling for the tapes of stringers of the kind described formed by folding and overlapping extended ends of the stringer tapes adjacent the and links at one or both ends of the stringer and securing said overlapped folded tapes together to form a bridging or coupling portion which will facilitate the attachment or mounting of the stringer tapes in connection with predetermined garments or other articles of manufacture, especially in the operation of stitching ,the fastener to its support; a further object being to provide an end coupling or bridging portion wherein the free end of each tape is severed along the diagonal fold line of the opposed tape and wherein the overlapped and folded end portions are secured together by a suitable adhesive preferably of the type which will readily harden and which will penetrate into the interstices of the braid of the tape to form a secure adhesion between the parts, especially in the presence of pressure; a further object being vto provide a. stringer tape having flexible couplings at each end thereof formed from the material of the tapes to provide the couplings and end stops at each end of the links, thereby facilitating stitching of the ends of the tapes to the support or supports therefor in close proximity to the end links on the tapes and eliminating the inconvenience heretofore experienced in attaching fastener stringers of this kind to their. supports and the breakage of needles caused by striking metallic parts or end stops at the stringer ends; and with these and other objects in view, the invention consists in a device of the class and for the purpose specified, which is simple in construction, efllcient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. 3 is a partial section on the line 3-3 of Fig. l; and,

Fig. 4 is a view similar to Fig. 1 showing another formof construction.

In the formation of separable fastener stringers, it is customary to attach the coupling links or scoops to one edge of the stringer in a given length and to link projecting ends of the stringer tapes at each end of the end links thereof, which projecting ends are usually trimmed off in the attachment of the stringer or stringers to a suitable support.

7 It is the purpose of my invention to utilize these protruding ends to form coupling or bridging endsat one or both ends of the stringers to provide a flexible coupling or bridging section which retains the stringer ends in predetermined spaced relation to'each other and provides a convenient means for attaching the fastener to its support at said end or ends.

In Figs. 1 to 3 inclusive, I have shown the invention applied to one end of a stringer, whereas in Fig. 4, the invention is applied to both ends of a stringer. In Fig. 1, 5 and 6 represent the stringer tapes which are coupled together by a suitable metallic or other coupling 1 adjacent the coupling links 8 and 9 at one end of the stringer, the links being preferably applied to enlarged or beaded edges l0 and II on said tapes. The coupling I forms an end stop for limiting the movement of a slider I! in one direction on the stringers, the sliderhaving a finger piece or pull i3 facilitating the operation thereof, as in other devices of this kind.

Secured to the beaded edges l0 and ll of the tapes 5 and 5 adjacent the end links 8 and 9 at the other end of the stringer are other end stops it and I5 and the tapes 5 and 6 normally project as seen at It and I1 in dot and dash lines beyond the couplings i4 and i5. adjacent surfaces of said projecting ends may be cut as seen at Ilia, lid to meet the fold line of opposed tapes, or these portions may be cut ofi after the folded tapes have been secured together, The projecting ends it and ll of the tapes are folded on the lines [6b, l'lb, and one upon the other to form a substantially triangular coupling end i8, and these overlapped folded ends are secured together by a suitable adhesive, preferably of the quick drying and cellulose type, providing a secure coupling or adhesion between said tapes, and the coupling or adhesion may be formed under pressure, and in the use of some adhesives, under heat.

In folding the projecting ends I 8 and i1 one upon the other on the lines i6b, "b, one side edge of each tape is brought into close proximity to the end stops I4 and I! as indicated at IS in Fig. l of the drawing, so as to permit the location of a line of stitching in close proximity to the edge I! as indicated by the dot and dash line 20 in Fig. 2 of the drawing. By simply Inner 7 employing the adhesive in securing the parts together, no dimculty is experienced in passing the stitches therethrough, and at the same time, the overlapped end portions of the tape will maintain their strength and rigidity without. being weakened by other lines of stitchings, which would be the case if said overlapped portions were stitched together. It will be understood at this time, however, that in some instances, stitchings may be substituted for the adhesive where the question of strength is not an important factor.

By providing a coupling of the kind described, the normally free ends ofa fastener stringer will be disposed with the end links in properly spaced relationship with respect to each other so as to avoid the diiliculty in improper attachment of the fastener to a garment. In some instances, the coupling may be used primarily for this purpose and the coupling severed between the inner beaded edges of the stringers after the fastener has been attached to a suitable support, which requires the separation of the stringer ends where'the coupling tape is employed. In this case, the tapes will be trimmed along edges substantially defined by the dotted lines II of Figs. 1 and 2 of the drawing, thus producing neat and finished edges. The importance of the foregoing is to facilitate bringing opposed surfaces of two supports to which the stringers are attached in proper relationship to each other when the fastener is in closed position and to prevent buckling or jamming of the links with the slider by improperly attached stringer ends.

However, the primary purpose of my invention is to provide a coupling which remains permanent, especially in the use of fasteners on supports having closed ends, such for example as on pockets, pocketbooks, various types and kinds of luggage, etc.

In Fig. 4 of the drawing, I have shown a slight modification wherein the end coupling 22 at one end of stringer tapes 23 and 24 is the same as the end coupling shown in Figs. 1 to 3 inclusive except that the end stops {4 and ll are removed and the coupling 22 is arranged in close proximity to the end links 25 and 26 and thus forms the end stop for the slider 21 employed for coupling and'uncoupling the links 25 and 28. with this construction, I also preferably remove the end stop 1 and employ another tape ,coupling 28 formed by folding the ends 230 and 14a of the tapes- 23 and 24 one upon the other on diagonal lines 23b and D, the same as in folding the tape ends it and I1, except that the ends of the tape are not out along the lines lia, Ila, -but are allowed to extend as clearly shown, to provide an added mounting of tapes upon the article or support to which the stringer is attached. It will be understood in this connection, however, that the extension of the strap ends 23a, 24a is not essential and both ends may be of the triangular form shown at the top of Fig. 4 of the drawing, depending entirely upon the use to which the invention is applied. For example, in attachment to a sprocket or to the opening of a tobacco pouch, the two triangular ends would be suilicient in most cases.

In overlapping and securing the tape ends together in the manner described and by the use of an adhesive, the ends remain ilexible and yet provide suflicient reinforcement to withstand the a thrust of the slider, and thereby act as a stop.
